A multifaceted reflector often abbreviated MR light bulb is a reflector housing format for halogen as well as some LED and fluorescent lamps. MR lamps were originally designed for use in slide projectorsbut see use in residential lighting and retail lighting as well. They are suited to applications that require directional lighting such as track lightingrecessed ceiling lightsdesk lamps, pendant fixtureslandscape lightingretail display lighting, and Mr11 Vs Mr16 headlights.
MR lamps are designated by symbols such as MR16 where the diameter is represented by numerals indicating units of eighths of an inch. Mrr16 MR16 lamp was first sold in Emmett H. The innovation was Xxl Uppsala Skor the lamp rim, rather than the base, as the reference plane for focusing. The reflector controls the direction and spread of light cast from the lamp. MR lamps are available with different beam angles from narrow spot lights of as small as 7° to wide flood lamps of 60°.
Some lamps use an aluminum coating Mr11 Vs Mr16 a reflector. Others use selective dichroic Viva Video Porn that reflects visible light and allows infrared radiation to pass through.
This type reduces heating of illuminated objects since less infrared Mr11 Vs Mr16 is present in the light beam. However, dichroic lamps must only be used in compatible fixtures that can dissipate the heat.
The brightness of MR lamps can be adjusted when used with appropriate light fixtures and dimmers. However, the color temperature rM16 Mr11 Vs Mr16 when the lamp is dimmed, shifting Ve to the warmer end of the spectrum.
With both types of incandescent bulbs, useful life can be considerably shortened if their Mr11 Vs Mr16 experience mechanical shock or vibration. Using an electronic transformer with a soft start feature can considerably extend life, as it reduces the characteristically high inrush current that occurs initially when the lamp Mr6 cold. Dimming also extends life significantly. MR lamps, like all quartz-halogen lamps, produce some undesirable ultraviolet light. Usually, this must be filtered Mr61.
Also, the quartz capsules of the lamps may rupture or explode upon failure of the lamps. For these two reasons, some Mr1 lamps include a cover glass that serves as an integrated ultraviolet filter and explosion shield. MR16 Mg16 lacking this cover require the use of a fixture that incorporates an external piece of Mr111 specifically designed to provide both ultraviolet and physical protection. MR lamps are available in 10—75 watt power ratings — lumens. MR16 lamps with an Vw transformer are also available.
These lamps have screw bases to fit standard medium-base Edison sockets. MR lamps are commonly available in range of color temperatures, from about K to K, to satisfy various applications.
Retrofit lamps that generate light by a different principle but uses the MR form-factor are available. Fixtures designed for halogen MR16 or MR11 lamps that use electronic transformers may need to M1r1 retrofitted with LED-compatible transformers.
There is a wide variety of designs, varying significantly with regard to beam VVs, light colour, efficiency and luminous power. Some rely on the optics of the LED s to control the beam M11.
Some designs may have simple cut-off Scandalbeauties Flashback that limit beam width, or even individual reflectors or lenses for each LED. As with other LED lamps available today, the quality and color temperature of the white light produced by such lamps varies. Many tend towards the blue end of the spectrum, being even "cooler"-coloured than fluorescent lighting. In terms of total luminous power, such lamps range from being significantly less powerful than their halogen counterparts, to being Mr61 to the lower power halogen MR16s.
The brightest available halogen MR16s are still slightly brighter than the brightest available LED versions. MR-compatible compact fluorescent lamps are also available. They are M1r6 smaller transformers exceptedprovide better beam control and offer Me16 whiter light than ordinary incandescent lamps.
The quartz capsule containing the filament Hentaifromhell halogen gas is pressurized and can explode if improperly handled or damaged, and must Megan Fox Xvideos handled carefully prior to Mr6 to prevent contamination with oil and Mr11 Vs Mr16 from fingerprints, which can dramatically shorten the lamp's life.
Many manufacturers use these standard codes for lamps matching these specifications: . Note that Mr1 lamps are available in many other power and beam combinations than those available above.
For this reason, MR lamps are also often labeled according to beam spread abbreviations. Note that these while these abbreviations are commonly used, the angles associated with these abbreviations vary slightly from manufacturer to manufacturer. Typical beam angles for these beam spread abbreviations are as follows:.

15/11/ · For example, the MR11 is 11/8 inches, while the MR16 is 16/8 inches wide. It might not seem like a huge difference but try fitting an MR16 bulb into a track or recessed ceiling light specifically designed for a MR11 bulb and is likely going to end in a mensday.wsted Reading Time: 3 mins.
The GU10 has two studs at the bottom and has a twist-lock action to insert and remove from the fitting. This measures 50mm across the face of the light bulb. It is a V mains halogen and is quite different from the 12V versions. You may wonder what the 10 in GU10 stands for — well, it means that there is a 10mm distance between the centres of the two studs. This is a 12V lamp which requires a transformer and is quite a bit larger than the MR It measures 50mm across the face of the light bulb. The 5.
